Pixel array for LC silicon light valve featuring pixels with overlapping edges

A receiver receives a signal transmitted by a time-division multi-access method that divides one frame into a plurality of communication slots in conducting communication. In this receiver, a detection circuit detects whether a received RF signal is stronger than a predetermined level. The received RF signal is demodulated by a demodulation circuit. An oscillation circuit generates a clock that is used to decode the data obtained by demodulation. The data obtained by demodulation is stored in a memory in synchronism with a clock reproduced from the received signal, and is then retrieved from the memory in synchronism with the clock generated by the oscillation circuit. This eliminates jitters. After jitter elimination, the data is decoded by a processing circuit. The writing/reading operation against the memory is initialized in accordance with a result output from the detection circuit.
